SOME BRED PARASITIC HYMENOPTERA IN THE 
IOWA AGRICULTURAL COLLEGE

BY ALICE M. BEACH. 
This list is prepared from the material in the collections of 
the Iowa Agricultural College and the Iowa Experiment Sta- 
tion, and may be considered a preliminary record of the parasi- 
tic Hymenoptera of the state. In its preparation the notes and 
records made by Prof. C. P. Gillette, while entomologist of the 
Experiment Station, have been freely consulted and largely 
drawn upon. The list is still incomplete for much material yet 
remains to be classified and records to be filled out.
